Radiator Question

In general, you can run more timing on an iron than alum head. Use the same plugs as the E7's unless you have P heads as they require a different plug. For Nitrous, go at least 1 step colder and check the plugs for signs of detonation. If memory serves me right- ASF32-C for the GT40 is one step colder than stock ASF42-C.

For most N/A, you are in the 12.5- 13 range. For a nitrous car 11.5-12. 14:1 IMO is too lean for a nitrous car. You can run rich all day long, but lean once. Lean + Nitrous + detonation= BOOM

You would have an na tuneup in the car all the time. When you go to spray you would set the timing back and away you go. You need a wet nitrous kit as the extra fuel needed will come from the nitrous kit not a carb jet change.

i love how it went from talking about radiators to how to tune my nitrous set up lmao

You Hijacked your own thread, classy lol

On a serious note, ...the advice already given is the way to go. However if you have a 160* installed and its running warmer than normal stats you most likey have air pockets all in the system. With a 160* its in open loop heaven with the computer, .....which is not good btw.
